Given numbers are 405,764,685,893
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,764,685,893 is 37854752220.
Find LCM of 405,764,685,893 with Prime Factorization
| 5 | 405, 764, 685, 893 |
| 81, 764, 137, 893 |
Multiply the prime numbers at the bottom and the left side.
5 x 81 x 764 x 137 x 893 = 37854752220
Therefore, the lowest common multiple of 405,764,685,893 is 37854752220.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
405 x 764 x 685 x 893 = 189273761100
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
764 : 1, 2, 4, 191, 382, 764
685 : 1, 5, 137, 685
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,764,685,893, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
764:2x 2x 191
685:5x 137
893:19x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 189273761100/(1x5)
LCM = 189273761100/5
LCM = 37854752220
Thus, we can understand that the LCM of 405,764,685,893 is 37854752220.
